Now things are getting interesting with the Pittsburgh Steelers.
Harrison has experienced discomfort in his surgically repaired left knee all week. Polamalu is nursing a calf injury.
Alan Robinson of the Pittsburgh Tribune-Review talked with Polamalu after the loss to the Denver Broncos and saw no hint of an injury or discomfort on the part of the star defender. It's possible he's being rested -- the veteran often missed practice last season only to play Sundays -- but Dulac's tweet wasn't subtle.
There is some concern about the overall age of Pittsburgh's defense, but the more immediate concern is getting these veterans healthy on a team that rests at 0-1 heading into a critical weekend.
